Very large scroll back buffer, which can be searched, saved, copied and printed.

HIGHLIGHT patterns: text sent by the host that matches a pattern can be highlighted in any foreground/background color combination.
An IVT script can be started automatically or by clicking on the highlighted text.
Example: A compiler error message is highlighted. Click on it and your favorite editor starts on the specified file and line number that are extracted from the error!

Marker pen: select text with the mouse, hit F3 and the text will be highlighted (so you can find selected bits on large screen easily).

Once you get used to creating sessions with a few clicks and switching between 10, 20 (or even more) parallel sessions without losing track, you’ll wonder how you ever got along without it :-)
